Apple's goal has always been to insure that our customers have a great experience with their iPhone and we know that jailbreaking can severely degrade the experience. As we've said before, the vast majority of customers do not jailbreak their iPhones as this can violate the warranty and can cause the iPhone to become unstable and not work reliably.

The Library of Congress decision today simply means that users can not be charged with violations of the DMCA for jailbreaking their iOS devices, a tactic Apple had never bothered to employ in attempting to squash the practice. Apple remains free, however, to discourage users by other means, including voiding product warranties due to violations of the terms and conditions all users must agree to before using their devices and software.

- allow owners of used cell phones to break access controls on their phones in order to switch wireless carriers.

- allow people to break technical protections on video games to investigate or correct security flaws.

- allow college professors, film students, documentary filmmakers and producers of noncommercial videos to break copy-protection measures on DVDs so they can embed clips for educational purposes, criticism or commentary.

- allow computer owners to bypass the need for external security devices called dongles if the dongle no longer works and cannot be replaced.

- allow blind people to break locks on electronic books so that they can use them with read-aloud software and similar aides.
